Patent number: 12543317Abstract: The present disclosure relates to a memory device that includes a substrate and source and drain regions formed in the substrate. The memory device includes a gate dielectric formed on the substrate and between the source and drain regions. The memory device also includes a gate structure formed on the gate dielectric and the gate structure has a planar top surface. The memory device further includes a multi-spacer structure that includes first, second, and third spacers. The first spacer is formed on a sidewall of the gate structure and a top surface of one of the source and drain regions. The second spacer is formed on a sidewall of the first spacer and the second spacer has a dielectric constant greater than a dielectric constant of the first spacer. The third spacer is formed on a sidewall of the second spacer and a horizontal surface of the first spacer.Type: GrantFiled: July 28, 2022Date of Patent: February 3, 2026Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Gulbagh Singh, Chen-Hao Li, Chih-Ming Lee, Chi-Yen Lin, Cheng-Tsu Liu

Patent number: 9337126Abstract: An integrated circuit and a method of fabricating the integrated circuit are provided. In various embodiments, the integrated circuit includes a first substrate, a second substrate, and a bump pad. The first substrate has at least one active device and a plurality of first metallic pads electrically connected to the active device. The first substrate has front-end-of-line processing layers without back-end-of-line processing layers over the front-end-of-line processing layers. The second substrate has a semiconductor substrate and an interconnect structure disposed on the semiconductor substrate, and the interconnect structure has at least one second metallic pad. The second substrate does not include any active devices. The bump pad is sandwiched by the first substrate and the second substrate. The active device and the first metallic pad of the first substrate are electrically connected to the second metallic pad of the second substrate through the bump pad.Type: GrantFiled: November 27, 2013Date of Patent: May 10, 2016Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Chen-Hao Li, Ying-Han Chiou, Chi-Yen Lin
